I finally managed to finish level 24, and also the whole 20s column which was a breeze. This means that with the levels I've finished before, I now have all the levels up to 49 completed. :joy:
49 is fairly easy until the last room which has switches up against the walls all surrounded by mines. It's easy to see what you have to do, but the slightest mistake kills you.
Well, I got stuck at 24's last room, so I started doing other levels randomly.
So right now (checks game), I finished the 00 and 10 columns, and reached for each column:
24, 38, 49, 54, 69, 74, 81, 96
